Sensory Processing and Executive Functioning in Autistic Adults

Area of Science:

• Neuroscience
• Psychology
• Autism Spectrum Disorder Research

Background:

• Adults on the autism spectrum often experience sensory hyper- and hyporeactivity.
• Executive functioning (EF) impairments are frequently observed in individuals with autism.
• Existing research suggests a connection between sensory processing difficulties and EF challenges.

Purpose of the Study:

• To investigate the relationship between sensory processing issues and executive functioning (EF) in adults.
• To determine if sensory processing problems predict EF impairments in autistic adults.

Main Methods:

• The study included 60 autistic adults (30 male, 30 female) and 44 neurotypical adults (20 male, 24 female), matched for intelligence and age.
• Self-reported sensory processing (using the GSQ-NL) and EF (using the BRIEF-A) were compared between groups.
• Correlational and regression analyses examined the link between sensory processing and EF.

Main Results:

• Significant differences in sensory processing and EF were found between autistic men and women.
• Hyporeactivity to sensory information was the strongest predictor of executive functioning problems in the autistic group.

Conclusions:

• Clinicians should recognize distinct sensory experiences in autistic adults compared to neurotypicals.
• Awareness of gender-based differences in sensory processing and EF is crucial for effective assessment and counseling of autistic adults.
